What’s new
-
To improve awareness and performance of early cardiopulmonary resuscitation (CPR), a network of first responders (i. e. firemen/police), national awareness campaigns and local initiatives to improve lay person CPR have been employed, including strategies to ensure 24/7 automated external defibrillator (AED) accessibility.
-
We found higher rates of bystander CPR and AED use in our current cohort of cardiac arrest patients than in a historical cohort, as well as higher survival.
-
Our findings support continued efforts to increase bystander CPR and AED use.
